The CRS is a Congressional "think tank" with a staff of around 700. Reports are commissioned by members of Congress on topics relevant to current political events. Despite CRS costs to the tax payer of over $100M a year, its electronic archives are, as a matter of policy, not made available to the public.

Individual members of Congress will release specific CRS reports if they believe it to assist them politically, but CRS archives as a whole are firewalled from public access.

This report was obtained by Wikileaks staff from CRS computers accessible only from Congressional offices.

Pakistani and some U.S. officials argue that Islamabad has taken a number of steps to prevent further proliferation of nuclear-related technologies and materials and improve its nuclear security. A number of important initiatives such as strengthened export control laws, improved personnel security, and international nuclear security cooperation programs have improved the security situation in recent years. Current instability in Pakistan has called the extent and durability of these reforms into question. Some observers fear radical takeover of a government that possesses a nuclear bomb, or proliferation by radical sympathizers within Pakistan's nuclear complex in case of a breakdown of controls. While U.S. and Pakistani officials express confidence in controls over Pakistan's nuclear weapons, it is uncertain what impact continued instability in the country will have on these safeguards.
